J 7,2505. v.5 62 I I ATTORNEY v wlTNE S v g Patented June 24, 1930UNITED; STATES PATENT OFFECE JACOB HELGESEN, OF WHITE PLAINS, NEW YORKGARBAGE CHUTE This invention relates to improvements in garbage chutes.

The primary object of the invention resides in a garbage receptacle forfacilitating the disposal of garbage in a sanitary manner withoutnecessitating a trip exteriorly of a building in which the device isinstalled, and which will be found convenient for use in hotels,restaurants, and hospitals, as well as for homes.

Another object of the invention is to provide a built in garbagereceptacle which includes a chute, access to which may be had from theinterior of a building through a door provided therein, while the lowerend of the chute enters an enclosed pit exteriorly of the buildinginwhich a garbage receiving can is placed to receive the garbage droppedinto the chute, the door when opened causing the actuation of anotherdoor within the chute to seal the same to preclude the odors of thegarbage can from escaping into the interior of the building.

Another object of the invention is the provision of a garbage chutethrough which a circulation of atmospheric air is passed to expel theodors therefrom, and inwhich a pipe spray is arranged to allow flushingof the chute as required.

With these and other objects in view, the

invention resides in certain novel construc-.

Application filed October 5, 1928. Serial No. 310,553.

Referring to the drawings by reference characters, the numeral 10designates the vertical outer wall of a building structure, 11 theflooring on the inside of the wall, and 12 a concrete foundation orbase, the latter having a pit 13 provided therein below the exteriorsurface level. The pit opens onto the surface through an opening 14 inthe top thereof which is normally closed by hinged door 15 having airopenings 16 therein.

' Installed on the interiorside of the wall 10 is a chute 17 which isconstructed of an upper casing section 18 which rises above the floorlevel and which has its lower end fitting within a casing section 19which depends below the plane of the floor 11 into arecess 20 in theconcrete base 12, which recess communicates with a' downwardly inclinedpassage 21 which enters the pit 13. A garbage receiving can A is placedin the pit to receive the garbage entering the same from the inclinedpassage of the chute, however, other cans may be stored .within the pitas they become filled and pending their removal by the garbagecollector.

The top end of the casing section 18 is formed with a right angularlydisposed neck 22 which extends through the side wall 10. A grating 23 ismounted on the outside-of the wall against the open end of the, neck 22ancl has baffle plates '24: which deflect the odors from the chutedownwardly and prevent the insertion of refuse into the chute from theexterior of the side walls. The inner top of the casing section 18 isinclined at an angle and has an opening 25 therein for register with anopening 25 in the housing 26 which fits against the wall 10 and floor 11and is anchored thereto by anchor screws 27.. The outer housi'n 26 maybe of a cast metal suitably porcelained to impart a clean and sanitaryappearance thereto. The housing conforms to the shape of the upperportion of the chute and is bolted thereto while a hinged door 28 ismounted thereon for sealing the opening 25.

The anchor screw 27 above mentioned is of a novel construction andincludes a. threaded shank 29 having an enlarged threaded head 30provided with a kerf 31.

The anchor screw is threaded into its supporting structure by insertinga screw driver into the kerf and turning the same, and after beingscrewed home, a rounded finishing head 32 is threaded to the head 30 ofthe screw.

For the purpose of sealing the chute upon opening of the door 28 toprevent odors from the pit from escaping into the build ing, I provide adoor 33 hinged to the rear wall of the casing section 18 adjacent thetop thereof. The door is of such length as to strike the front wall ofthe casing section when in a closed position, in such a manner that thedoor is rearwardly inclined. The door 33 is operatively connected to thedoor 28 by a flexible chain 34, whereby, opening of the door 28 todeposit garbage in the chute will cause the sealing .of the chute by thedoor 33. The deposited garbage will be supported by the door 33, butwhen the door 28 is closed, the door 33 will automatically drop underits own weight and release the garbage to the bottom of the chute.

For keeping the interior of the chute "in a sanitary condition, I mounta pipe spray 35 within the chute at the top thereof and which isconnected with a water supply pipe, the flow thereto being controlled bya regulating valve 36. The water discharged from the spray pipe whenturned on, washes down the inner side walls of the chute to effectivelyclean the same, while the bottom of the pit 13 has a drain 37 thereinfor carrying off the water during a spraying operation. The chute may bcflushed as often as is necessary.

. seen that when the door 28 is in theposition shown in full lines inFigure 3 of the draw mg, atmospheric air will circulate through thechute and pit to prevent the accumulation'of odors therein, while anyodors which may be present inthe chute are sealed upon opening of thedoor '28 to deposit refuse therein. As the garbage can A becomes filled,it may be removed upon opening of the door 15 and an empty cansubstituted therefor, or the filled cans may be stored in the pitpending their removal by the garbage collector.

lVhileI have be the most desirable embodiment of my invention, it isobvious that many of the details may be Varied without in any waydeparting from the spirit of my invention, and I therefore do not limitmyself to the exact details of construction herein set forth nor toanything less than the whole of my invention limited only by theappended claims.

hat is claimed as new is 1. In a garbage chute, an enclosed chute,

From the foregoing description, it will be described what deem to oneend of which opens directly to the atmosphere, a pit at the bottom ofsaid chute, an openable cover in the top of said pit, a door at the topof said chute through which refuse may be deposited upon opening of thesame, and means operable upon the opening of said door for sealing thelower end of said'chute therefrom, said cover having ventilatingopenings therein for circulating atmospheric air through said chute andpit when said door is in a closed position. 7 2. In a built-in garbagechute, the combination of a building structure having a side walland afoundation, a chute having its upper end opening through said side wallto the atmosphere, a pit in said foundation into which the lower end ofthe chute enters, a door for access to said pit, and

a door in said chute through which refuse 1 said chute through whichrefuse may .be de posited into said chutev upon opening of the same, andchutesealing means for sealing said chute below said door upon openingof the latter to prevent odors from the pit and lower end of said chutefrom passing said open door. v

i. In a building structure, a pit exterior-1y of the same below thelevel of the earths surface, a perforated cover in the top of said pit,a chute having its lower end opening into said pit and its upper endopening to the atmosphere whereby air may freely circulate through saidchute, a door in said chute accessible from the interior of saidbuiiding structure, and means operable by the opening of saiddoorforsealing said chute below the same, substantially as and for thepurpose specified.

In testimony whereof I have affixed signature Sept. 5, 1928.

JACOB HELGESEN.
